Description

Bisher war es bei Abstechstählen üblich, sowohl die schneidende Vorderkante als auch die Seitenkanten zu unterschneiden. Dadurch wird aber der Abstechstahl geschwächt. Es ist auch bekannt, Stähle mit nach der Mitte zu verjüngten Querschnittsformen zu verwenden, deren Kanten ein Stück gerade sind. Diese Stähle sind aber von rhomboidischer Form, so daß sie nicht als Abstechstähle zu ίο verwenden gehen, weil die Seitenkantien schräg verlaufen.Up to now it was common for parting tools to undercut both the cutting front edge and the side edges. Through this but the parting tool is weakened. It is also known to have steels facing the middle to use tapered cross-sectional shapes, the edges of which are slightly straight. These steels are, however, of a rhomboid shape, so that they cannot be used as parting steels ίο go to use because the side edges are sloping get lost.

Die Erfindung besteht nun darin, daß beiThe invention consists in that at

Abstechstählen die Seitenflanken des Stahls an den oberen und unteren Kanten ein kurzes Stück senkrecht zur Ober- und Unterkante stehen.Parting off the side flanks of the steel at the top and bottom edges a short distance Stand perpendicular to the top and bottom edge.

Auf diese Weise werden die Kanten des Stahls erheblich verstärkt.This way, the edges of the steel are significantly reinforced.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigen:The subject of the invention is shown in the drawing, for example. Show it:

Abb. ι bis 3 verschiedene Querschnittsformen undFig. Ι to 3 different cross-sectional shapes and

Abb. 4 eine Seitenansicht des Abstechbtahls. Fig. 4 is a side view of the parting tool.

Die Ober- und Unterfläche 1 und 2 des Stahls sind gleich breit, so daß der Stahl eine rechtwinklige Querschnittsform besitzt. Zwischen Ober- und Unterfläche ist der Stahl eingeengt. Der Stahl kann in schräger hängender Lage eingespannt werden, ohne daß der Stahl dabei an seiner Schneidfähigkeit einbüßt oder im Werkstück drängt, da durch die Einengung in den Flanken des Stahls ■eine unter sich verlaufende Form des Stahls entsieht. Die Kanten. 3, 4, 5 und 6 des Stahls sind ein kurzes Stück senkrecht zur Ober- und Unterkante des Stahls angeordnet. Beim Nachschleifen der Stirnseite dies Stahls werden die Flanken selbst nicht geschHffen und demzufolge nicht verändert. Bricht der Stahl etwa in schräger Linie ab, und zwar ist dies regelmäßig der Fall, so kann derselbe umgedreht werden, so daß die Kante 2 nach oben zu stehen kommt. Wenn die Stirnkanten wie in Abb. 4 geformt werden, so kann der Stahl, ohne geschliffen werden zu müssen, dreimal gewendet werden.The top and bottom surfaces 1 and 2 of the steel are equally wide, so that the steel one possesses rectangular cross-sectional shape. The steel is between the upper and lower surfaces constricted. The steel can be clamped in an inclined hanging position without the steel loses its cutting ability or pushes through the workpiece the constriction in the flanks of the steel ■ a shape of the steel running under it withdraws. The edges. 3, 4, 5 and 6 of the steel are a short piece perpendicular to the top and lower edge of the steel. When regrinding the face, this becomes steel the flanks themselves are not created and therefore not changed. The steel breaks approximately in an inclined line, and this is regularly the case, it can be turned over so that the edge 2 is facing up comes to stand. If the front edges are shaped as in Fig. 4, the steel, can be turned three times without having to be sanded.
